Patent No. EP2243229 (titled "Method And Apparatus For Conveying Antenna Configuration Information Via Masking") was filed by Nokia on Jan 7, 2009. The application was issued on Aug 31, 2022.
Determining antenna configuration and transmission diversity scheme through a novel bit masking approach. The method employs a set of bit masks derived from optimized hamming codes and bit diversity metrics, where the masks are specifically designed to maximize diversity while minimizing false detection. By applying these masks to cyclic redundancy check (CRC) bits, the method enables reliable detection of antenna configurations and transmission diversity schemes without requiring explicit transmission information. This approach eliminates the need for user equipment to analyze reference signals or perform complex demodulation, providing a more reliable method for determining antenna configurations and transmission diversity schemes.
